Card Games – Trigonometric Functions
This document includes a collection of card games.
1.
Periodic Functions Cards: Cards depicting various
transformations of y = sinx are provided. Identify the key
properties (amplitude, period, maximum & minimum values) of
each graph and match graphs that share common key
properties.
2.
Key Properties of the Sine Function Cards: Explore the key
properties of y = sin x by matching cards depicting the name of
each key property with a visual image, value or brief description,
and definition. Variations of this game include Memory Match
and Go Fish.
3.
Relations Cards: Classify various graphs and contextual
situations as either linear, quadratic, periodic or other. Determine
whether or not each relation is a function.

Key Properties of the Sine Function cards
The set contains 44 cards, four cards for each key property.
Each key property has a card depicting:
• property name
• visual image
• value or brief description
• definition
The cards can be used in a variety of ways.
Suggestion 1
Pick one of the cards. Find all cards that depict the same key property.
Suggestion 2
Play a version of Memory. Turn all cards face down. Pick two cards. If they
depict the same key property, keep them. Otherwise, return them to the table
face down. (This could be played solitaire or with others.)
Suggestion 3
Use the cards to play any card game where matching is required.
Go Fish, for example, could be played. Each player is dealt a number of cards
(7). In turns, each player asks others for cards with the same key properties as
one he/she is holding in his/her own hand. When a player collects all four cards
representing a key property, the set is put down in front of them. The player with
the most sets in the end wins.
Other card games, or solitaire games requiring matching could be adapted.
Suggestion 4
Use the cards to pick random groupings for the class. Each student draws a
random card. Students with cards that match the same key property form a
group.
Notes:
The PDF of the cards were designed using the same size as Avery Business
Cards – style # 05371. A custom back is provided as the final page in this PDF
if you wish to run the sheet of cardstock through the printer twice.
The first ten properties are depicted in the four full pages (each property is in the
same relative position on each page) – the eleventh property is on the following
half page. (The custom back is the final page.)
